Does anyone know what NPM does to determin the hourly stats once the detailed retention period is passed? I'm asking because when I pulled a report on one of my routers while I had the detailed stats the peak utilization was 98%. When I pulled the same report after the detailed statistics retention period was over the peak utilization was 78%. I though that the hourly stats retained the max within the hour, but it looks like I'm wrong. Any help is appreciated..
